This function was implemented in dd4950f36d
which added a "key" field, but that field was never used anywhere, and
still appears unused.

The channel ch.C is never closed.
Added the listen of the ch.Done() to guarantee
that the goroutine is exiting once the event channel
is closed

With the introduction of networkdb, the node discovery events were not
sent to the drivers. This commit generates the node discovery events and
sents it to the drivers interested in it.

Network DB is a network scoped gossip database built
on top of hashicorp/memberlist providing an eventually
consistent state store.
It limits the scope of the gossip and periodic bulk syncing
for table entries to only the nodes which participate in the
network to which the gossip belongs. This designs make the
gossip layer scale better and only consumes resources for the
network state that the node participates in.
Since the complete state for a network is maintained by all nodes
participating in the network, all nodes will eventually converge
to the same state.
NetworkDB also provides facilities for the users of the package to
watch on any table (or all tables) and get notified if there are
state changes of interest that happened anywhere in the cluster when
that state change eventually finds it's way to the watcher's node.
